Incident of oil leakage and theft in oil tank often happens. To prevent it, the liquid volume
insides the tank needs to be monitored continuously. Aim of the study is to calculate the
liquid volume inside oil tank on any road condition and send the volume data and location
data to the user. This research use some ultrasonic sensors (to monitor the fluid height),
Bluetooth modules (to sent data from the sensors to the Arduino microcontroller), Arduino
Microcontroller (to calculate the liquid volume), and also GPS/GPRS/GSM Shield module (to …
